Ok, first are you going to turbo your existing N/A motor or get another 7MGTE?
If it's your existing motor, there's two ways to do it. I don't know all the specifics but basically you can get the I/C/turbo/exhaust manifold off a turbo along with a MAFT system I believe (lemme know if I'm wrong about the MAFT).
The other BETTER way is same as above but get the ECU off the turbo as well, might need wiring harness too but not sure. I'll see if I can find more info on some of the other websites I go to, I'm sure someone has a writeup.
If you're doing a whole engine swap, here's a good link
